While it seemed like a fun prank at the time, I realize my prank fire extinguishers full of leaded gasoline were a mistake.

I don't get the diverging diamond interchanges one

Diverging diamond interchanges are a type of road intersection that appears very chaotic from the outside, but are actually pretty simple and safe to navigate

Diverging diamonds are great if your only consideration is car throughput.

If you are considering people walking or riding bicycles, they are shit.

It doesn't help that US diverging diamonds seem to insist on having pedestrians walk through the median.

But honestly all interchanges are varying degrees of horrible and if you want your city to be bearable to navigate as a pedestrian/cyclist you just really don't want to do urban highways, or roads above a certain size in general.
